FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION formingpart of Letters Patent N 0. 395,321, dated January1, 1889.

Application filed October 10, 1888.

Toall whom it may concern.-

Be it known that 1, JAMES S. FISHER, a citizen of the United States,residing at Chicago, in the county f Cook and State of Illinois, haveinvented a certain new and useful Improvement in \Vindow Sash Fasteners,of which the following is a specification.

The object of my invention is to provide windows with means whereby theymay be SQ? cured automatically against attempts to open them from theoutside, and held motionless in their frames.

The intention consists in the combination of a metal stop andself-adjusting catch, so constructed that when respectively attached, ashereinafter indicated, to the upper and lower sashes of a window theywill when the window closed press tightly against each other and holdthe respective sashes immovable.

The accompanying drawings explain the mechanism of my invention andpermit its operation to be defined, as follows:

Figure 1 represents a wimlow-frame and my invention attached to theclosed sashes. Fig. 2 is a detailed sectional View of the up per andlower sashes of a window when closed, showing my invention attached.

In both figures similar letters indicate similar parts.

A represents the upper sash; Aithclower.

B is a metallic plate provided with a knob, b hinged at a to B, anothermetallic plate projecting from the plate B and turned upward around thehinge u prevents the plate B from touching the side of the upper sash,A.

b is a flat metallic spring riveted at l) to B and holding the twohinged plates B and B apart, pressing with its free end against theplate B.

Z) is a narrow strip of metal riveted at 11 between the spring Z) andthe plate B, and at its free end so turned as to clear the hinge a andact as a guard against the plate I3 being drawn back too far against thespring Z).

Serial No. 287,705. (No model.)

b is a cord which may be attached at one end to the knob b and providedfor ornament with a tassel at its other end, and affording a means ofdrawing back the plate Bin the case of a high window-sash.

B B is a metal plate to be sunk into the upper sash and screwed theretoin such a position as to bring its upper end, which is pro vided with araised ledge, closely against the free end of the plate B when thewindow is closed.

B B in combination with the plates B and B, hinged at a, with the springI), riveted to the plate B, all constructed as hereinbefore stated,constitute my invention. When the sashes are closed, the ledge B tightlyengages the upper end of the plate B and the spring I) presses saidplate B against the ledge. In order to open the sashes, the plate B isdrawn back, when the sashes may be respectively raised or lowered. Whenthe sashes fit closely, I cut away from the outside of the lower sash asmall groove, in which the ledge 113 runs.

The peculiar advantage and utility of my invention are its strength,ease of operation and of attachment to window-sashes, and the securityby it automatically afforded to win dows, together with its ornamentaldesign.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

The combination of a metallic plate with raised ledge B B being securedto the side i of an upper window-sash with a metallic firmly scrcwed,asrepresented in Fig. 2,to the 1 top of the lower-sash and at its side.Atongue 1 hinge, I; a B, the arm B having its upper end free and beingprovided with a projecting knob, 11*, the arm B being secured to theupper frame of the lower window-sash beneath the ledge 13*, and beingprovided with a flat metal spring, I), which presses the free end of Bagainst the ledge B substantially as set forth.

JAMES S. FISHER.
